Improvement in self-closing cocks and faucets



UNITED STATES B TE-1gp JOHN BROUGHTON, OF BROOKLYN, NEW-YORK.

IMPROVEMENT IN-SELF-OLOSING COCKS AND FAUCETS, etc

Specification forming part of Letters Patent No. 212,436., dated February 18, 1879; application filed January 14, 1879.

To all whom it may concern:

Be it known that I, JOHN BROUGHTON, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Self-Closing Cocks, Faucets, &c., of which the following is a specification:

whereby the several parts of the cook or faucet are properly guided in their operation, whereby the cook or faucet may be operated by turning the key either to the right or left, and whereby economy of parts and cheapness of construction are effected.

In the accompanying drawings, Figure 1 represents a central longitudinal section of a faucet embodying my improvements; Fig. 2, a front view thereof, and Fig. 3 a perspective view of the key of said faucet when detached.

Similar letters of reference designate corresponding parts in all the figures.

A designates the body or shell of a cook or faucet, and a aport through which the water passes as it is drawn from the faucet. B designates a disk-valve, of the kind commonly employed in self-closing faucets. This valve is secured to a valve-stem, O, which passes through the bonnet or plug D in the top of the faucet. When not otherwise actuated the valve is kept tightly closed by a spring, E, here shown as of spiral form, coiled around the stem 0, and confined between the valve B and bonnet or plug D. The opening in the bonnet or plug D, through which the stem 0 passes, may be packed by a cup-washer or in any suitable manner.

F designates a head, shown as formed in one piece with the stem 0, and which comprises ears b, shown as projecting from its opposite sides. G designates the key of the faucet,- consisting of a shaft, 0, provided at one end with a handle, d, whereby it may be turned. H designates a yoke, shown as formed in one piece with the key G. In this yoke I preferably make an opening, through which the stem C passes, and it is provided with liftingpieces 6, which act on the ears I), to raise the valve B. The yoke H is preferably also formed with cheek-pieces f, (shown clearly in Fig. 3,) between which the head F fits, and by which it is properly guided in its movements.

The shaft 0 of the key G fits in half-round or open bearings g, which are shown as formed in one piece with the bonnet or plug D, and in which the key may be freely turned or oscillated. The downward pressure exerted by the spring E serves to hold the key G in the bearings 9.

By my invention I produce a faucet in which the parts are properly guided and held in position by each other, and can consequently be made cheaply, and put together with very little difficulty by an inexperienced person.

Although here shown embodied in a faucet, these improvements are equally applicable to stop-valves, relief-valves, 850.

While I prefer to use two ears and two lifting-pieces to make the key double-acting, it is practicable to use only one car on the head of the stem and one lifting-piece on the key, in which case the key is only single-acting.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a self-closing cook or faucet, the combination of two ears, projecting from opposite sides of the head of thevalve-stem, and ayoke provided with two lifting-pieces to operate, one upon each of said ears, whereby the valve may be opened by turning the yoke either to the right or left, substantially as specified.

2. In a self-closing cook or faucet, the combination of a valve-stem provided with ears on opposite sides of its head, and a yoke havinga central opening, through which said stem passes, and provided with lifting-pieces for acting on the said ears to raise the valve, sub stantially as specified.

3. In a self-closing cook or faucet, the combination, with a valve-stem provided with one or more ears, of a yoke provided with one or more lifting-pieces for acting on' the ears to raise the valve-stem and cheek-pieces for guiding the stem, substantially as specified.

4. In a self-closing cook or faucet, the combination of a valve-stem provided with one or bination of the valve-stem 0, spring E, head 1n0relears,'a key mounted in half-round or F, with its ears I), yoke H, with its liftingopen bearings extending from the cook or pieces 6, and cheek-pieces f, substantially as faucet, and carrying a yoke for acting upon specified.

the ear or ears to raise the valve, and a spring for closing the valve, and serving also to retain JOHN BROUGHTON' said key in its bearings, substantially as speei- Witnesses: fied. T. J. KEANE,

5. In a self-closing cook or faucet, the com- FRED-HAYNES.
